Multiple Allelism using ABO Blood Groups — one of the most asked NEET topics. 📌 Topics Covered: • What is Multiple Allelism? • Three alleles: IA, IB, and i; dominance: IA = IB is greated than i • All 6 genotypes and 4 phenotypes • Inheritance pattern across generations • NEET MCQ on blood group genetics Transcript with Timestamp 0:00 Introduction — Multiple Allelism 0:52 Definition: more than 2 alleles controlling one character 0:59 Example: ABO blood groups — 3 alleles (Iᴬ, Iᴮ, Iᴼ) 1:41 6 possible genotypes → 4 phenotypes 2:27 Iᴬ and Iᴮ dominant; Iᴼ recessive 4:09 Summary: 3 alleles, 4 phenotypes, 6 genotypes 7:03 Problem: Father A (heterozygous) × Mother B (heterozygous) → 4 possible blood groups in offspring 9:22 Father homozygous A × Mother homozygous B → 100% AB offspring Complete Study Notes (11th and 12th) are available at: https://amzn.to/3K4Li7k Complete Study Notes for 12th are available at: https://amzn.to/3PRhWjm Complete Study Notes for 11th are available at: https://amzn.to/4uw1hBa The study notes for this unit Genetics & Evolution are available at https://amzn.to/2Sh27jW The study notes for other units: - Diversity in Living World - https://amzn.to/3r8qkyH Structural Organisation in Plants and Animals - https://amzn.to/3r2cxmZ Cell: Structure and Functions - https://amzn.to/2GPagcm Plant Physiology - http://amzn.to/2EZR5HS Human Physiology - http://amzn.to/2DA46ea Reproduction - https://amzn.to/2wu43eS Biotechnology - http://amzn.to/2EZyqf9 Biology in Human Welfare https://amzn.to/4dPRZd7 Ecology https://amzn.to/3RwuOvF ____________________________________________ For business inquiries: [email protected] ___________________________________________ #MultipleAllelism #ABOBloodGroup #BloodGroupGenetics #NEETBiology #GeneticsClass12 #NeelaBakoreTutorials
